One of the most popular gemstones of recent times, tourmaline is a wonderful gemstone that has many excellent properties. It occurs in almost every color imaginable, sometimes even with multiple colors in the same stone! Because of this huge variation in color it was often previously confused with other gems such as emerald and ruby. A wide variety of trace elements in the stone (such as manganese, iron and copper) are what cause the amazing range of colors. Most gem tourmaline is of the variety called elbaite. Major African sources for tourmaline include Mozambique, Zambia, Nigeria and Namibia. There are smaller deposits in Tanzania and Madagascar. Most of the individual sources produce stones of various colors. Aside from the more conventional pink and green tourmalines, the gem is also found in a range of fancy colors. These include yellow, orange, grey, apricot, peach and white. If you are looking for a unique tourmaline, this is where to look! Tourmaline has a very good hardness of 7.5, making it great for all jewelry applications. Because the gem often forms as long slender crystals, the most common cuts for tourmaline are rectangles and emerald cuts. Tourmaline is sometimes heat-treated to improve the color. This treatment is permanent and undetectable and has no effect on value or durability. Tourmaline is the birthstone for October, along with opal.
